wt32-eth01 (V1.4 PCB) Lan Error

I actually managed to make it work:

import network
import machine
lan = network.LAN(mdc=machine.Pin(23), mdio=machine.Pin(18), phy_type=network.PHY_LAN8720, phy_addr=1, power=machine.Pin(16), id=0)
lan.active(true)
lan.ifconfig()

Two crucial things:
a) the power pin is 16,
b) you must not have tried to create another network.LAN (the error changes if you try it twice with wrong parameters, so it gives off that it is not stateless). I think it keeps state even across soft reboots. Always disconnect power, reconnect, and start fresh.
